#include <stdio.h>

int x, y, z;

main()
{
	for(x=1; x<=7;x++)
	{
		for(y=2; y<=7;y++)
		{
			for(z=3; z<=7;z++)
			{
				if(x != y & x != z & y != z & y !=x & z!= x & z != y)
				{
				
				printf("%d%d%d\n", x, y, z);
		  		}
			}	
		}	
	}

}

if(x != y || x != z || y != z|| y !=x||z!= x||z != y)

Get's rid of 123 and 321 so your logic whether its && or || is lacking.
